Analysis of the Incidence of Diseases Occurring in an Inland Relief Group during the First Four Weeks after Entering Tibet

Objective To analyze the incidences of diseases occurring in an inland relief group during the first four weeks after entering Tibet. Methods The inland rescue group consists of 1769 members,and the hypoxia adaptation training was applied to all members for three months before travelling to Tibet. After entering simulated disaster zone with an elevation of 4000 meters,and collected the patients' name,age,diagnosis and other information within 4 weeks,then compared and analyzed. Results The leading three diseases were otorhinolaryngologic diseases,digestive diseases and respiratory diseases,and the corresponding percentage was15. 55%,12. 49% and 11. 02%,and constituent ratios of these three kinds of diseases were 29. 38%,23. 61% and 20. 83%. The incidence of acute high altitude diseases was 4. 92%,and the corresponding constituent ratio was 9. 29%,which included six cases of acute high altitude cerebral edema; the incidence rate of overall diseases in the first two weeks was high,and after that the incidence rate decreased gradually. Conclusions Hypoxia adaptation training under hypoxia was necessary for decreasing the incidence rate of acute high altitude diseases in rescuers; the first two weeks was the high incidence period of overall diseases and also for acute high altitude diseases.
